“…In this discussion, the authors considered the flow past an exponentially convective stretched surface and employed the semi-analytical technique homotopy analysis method (HAM) to determine the solution of the modeled problem. Gurivireddy et al (2016) highlighted the effect of thermal diffusion on MHD heat and mass transfer flow through a semi-infinite moving vertical porous plate with heat generation and chemical reaction. With these concerns in mind, Ojemeri et al (2023) recently investigated the hydromagnetic flow of an electrically conductive Casson fluid driven by radiation factor in an upstanding porous channel.…”

The analytical solution of heat transfer and hydro magnetic flow for an incompressible, electrically-conducting, and viscous dissipative fluid traveling vertically through an isothermally heated parallel plate in a slit micro-channel is performed. One channel surface was super-hydrophobic slip and temperature jump, whereas the other did not. This study also examined the effects of super-hydrophobic slip and a temperature jump on characteristic flow of magneto-hydrodynamics (MHD) free convection flow with viscous dissipative fluid. The perturbation technique was used to solve the coupled nonlinear and coupled equations analytically. With the aid of illustrative graphs, the results were presented, and the effects of the relevant controlling parameters namely Brinkman number, magnetic field, velocity slip condition and temperature jump effects were analysed for temperature, velocity, skin friction and Nusselt number distributions when either wall is heated by constant wall temperature. The result demonstrated that the activities of Brinkman number, Br, substantially increase fluid velocity, whereas growing levels of magnetic field effect was seen to slow down the flow movement. In addition, the fluid velocity is higher for greater values of temperature jump and velocity slip effects respectively. Furthermore, this research can prove very useful for designers in improving the performances of mechanical systems when viscous dissipation is involved, as well as heat transfer in micro-channels, as it is in combustion.

The current study analyzes the implications of an Arrhenius‐controlled heat transfer fluid on free convection in a micro‐channel confined by two immeasurable vertical parallel plates that are electrically non‐conductive due to an induced magnetic field (IMF) effect. The governing coupled nonlinear equations are ordinary differential equations, and the dimensionless steady‐state solutions were determined using the homotopy perturbation method (HPM). The derived results were discussed and represented graphically with the help of illustrative line graphs for momentum, IMF, temperature, and volume flow rate for the major controlling parameters, namely arrhenius kinetics, rarefaction, wall ambient temperature difference ratios, and Prandtl magnetic number. Thermo‐physical properties that are of engineering interest, like sheer stress and Nusselt number, are also computed and displayed. It is pertinent to report that the velocity of the fluid increases as a result of chemical reactions and rarefaction factors, whereas strengthening the Prandtl magnetic number decreases the volume flow rate. Also, numerical data was obtained and presented in tabular form to compare this research outcome to those of Jha and Aina, and great consistency was found. Microelectronics and microfluidics are some areas where this study can find relevance.

An analytical study of heat and mass transport in magnetohydrodynamic convective flow over an indefinitely long porous plate, which is vertically immersed in the porous medium, is investigated when heat sink, diffusion‐thermo, and thermal radiation are present. A magnetic field with uniform strength has been applied transversely directed into the fluid region. Analysis of diffusion‐thermo impact within the flow problem with constant heat and constant mass flux in the presence of thermal radiation and heat sink is the novelty of the current work. By using the Eckert number E as the perturbation parameter, the regular perturbation approach is used to solve nondimensional governing equations. On the flow and transport characteristics, the effects of Prandtl number, Grashof number, Eckert number, Dufour number, Schmidt number, radiation, magnetic field, and heat sink parameter have been investigated graphically and in tabular form, respectively. The innovative aspect of the current study is the inclusion of the Dufour effect, in addition to constant heat and mass flux at the plate. The Dufour effect can be utilized to improve separation processes, such as distillation, extraction, and chromatography. When the Dufour number and radiation parameter increase, the fluid velocity increases, and while the heat sink parameter increases, it decreases. As dissipation increases, the velocity of the fluid also increases. The concentration of the fluid is enhanced as mass diffusivity increases. When the heat absorption sink grows, the temperature of the fluid decreases.
